| 摘 要： | 从理论、计算方法和计算结果等方面分析了已有的三种剩余非均匀性(即剩余误差)计算方法的不足,根据探测器非线性响应原理,提出了一种新的方法。以实验数据对有关方法进行了验证,结果表明新的方法更为简单且更符合实际。与以前理论比较,推导出了近似公式。

Calculation of residual nonuniformity for infrared focal plane array |
| |
| Abstract: | The shortages of current three methods of residual nonuniformity (residual error) calculation for infrared focal plane array are analyzed in aspects of theoretical premises, calculation methods and results, etc. Based on the response nonlinearity of infrared detector, a new algorithm is proposed. It is proved that this algorithm is more concise and more accordant to experiments. In comparison with the previous theories, a proximate formula is also deduced. |
